Revision of Class E Airspace; Gillette,

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: This action will revise the 

Class E airspace at Gillette, WY. 

Additional Class E airspace is necessary 

to accommodate aircraft using a new 

Area Navigation (RNAV) Global 

Positioning System (GPS) Standard 

Instrument Approach Procedure (SIAP) 

at Gillette-Campbell County Airport. 

This will improve the safety of 

Instrument Flight Rules (IFR) aircraft 

executing the new RNAV GPS SIAP at 

Gillette-Campbell County Airport, 

Gillette, WY. 

DATES: Effective Date: 0901 UTC, May 

10, 2007. The Director of the Federal 

Register approves this incorporation by 

reference action under 1 CFR part 51, 

subject to the annual revision of FAA 

Order 7400.9 and publication of 

conforming amendments.

SUPPLEMENTARY INFORMATION: 

History 

On August 11, 2006, the FAA 

published in the Federal Register a 

notice of proposed rulemaking to revise 

Class E airspace at Gillette, WY, (71 FR 

46133). This action would improve the 

safety of Instrument Flight Rules (IFR) 

aircraft executing this new RNAV GPS 

approach procedure at GilletteCampbell County Airport, Gillette WY. 

Interested parties were invited to 

participate in this rulemaking effort by 

submitting written comments on the 

proposal to the FAA. No comments 

were received. 

Class E airspace designations are 

published in paragraph 6005 of FAA 

Order 7400.9P dated September 1, 2006, 

and effective September 15, 2006, which 

is incorporated by reference in 14 CFR 

part 71.1. The Class E airspace 

designations listed in this document 

will be published subsequently in that 

Order. 

The Rule 

This action amends Title 14 Code of 

Federal Regulations (14 CFR) part 71 by 

revising Class E airspace at Gillette, WY. 

Additional controlled airspace is 

necessary to accommodate IFR aircraft 

executing a new RNAV (GPS) approach 

procedure at Gillette-Campbell Airport, 

Gillette WY. 

The FAA has determined that this 

regulation only involves an established 

body of technical regulations for which 

frequent and routine amendments are 

necessary to keep them operationally 

current. Therefore, this regulation: (1) Is 

not a ‘‘significant regulatory action’’

under Executive Order 12866; (2) is not 

a ‘‘significant rule’’ under DOT 

Regulatory Policies and Procedures (44 

FR 11034; February 26, 1979); and (3) 

does not warrant preparation of a 

regulatory evaluation as the anticipated 

impact is so minimal. Since this is a 

routine matter that will only affect air 

traffic procedures and air navigation, it 

is certified that this rule, when 

promulgated, will not have a significant 

economic impact on a substantial 

number of small entities under the 

criteria of the Regulatory Flexibility Act.
